contained in the liquid discharged will speed up the process of wearing and tearing and accelerate the drop in
performance. If the unit is operated properly, it will not require any maintenance. Where applicable, you may clean
the hydraulic part from sediments and dirt. This can be done by counter-flushing the unit with clear water using a
hose to be connected through the pressure port of the pump. To remove tenacious dirt, the foot of the pump (8)
can be removed by loosening the screws located at the bottom of the pump. To avoid any hazard, any further
disassembly as well as the replacement of parts must only be done by the manufacturer or a by an authorised
service provider. Water left in the pump may freeze in case of frost and thus cause considerable damage.
Therefore, the pump must be removed from the liquid being discharged and fully drained when temperatures are
below the freezing point of the liquid. Please store the pump in a dry, frost-protected place. In the case of
malfunction, you should first of all check whether it was caused by an operating error or some other reason which
cannot be attributed to a defect of the device - for instance a power failure. The list below shows some possible
malfunctions of the device, possible causes and tips on their elimination. All the measures referred to may only be
carried out with the pump being separated from the electrical mains. If you yourself feel unable to eliminate any of
these malfunctions, please contact the customer service department or your point of sales. Any repair beyond the
scope specified below must only be performed by qualified staff. Please bear in mind that all warranty claims will
become void in the case of damage caused by inappropriate repair attempts, and that we decline any liability for
any ensuing damage.

ELIMINATION
1. Please use a device complying with GS
(German technical supervisory authority)
to check for the presence of voltage
(safety information to be observed!).
Please verify the correct position of the
plug.
2. Separate the pump from the electrical
mains, allow the system to cool down,
eliminate cause.
3. Please contact the customer service
department.
4. Eliminate blocking of pump wheel.
5. Please contact the customer service
department.
1. Remove possible congestion.
2. Remove possible congestion.
3. Start pump several times so that the entire
air will be driven out.
4. Make sure that the minimum suction level
is not fallen short of; if necessary, adjust
floating switch properly or make sure that
it can move freely; in the case of a
defective floating switch, please contact
customer service.
5. Eliminate blocking of the check valve (non-
return valve) or replace, if damaged.
1. Please use a device complying with GS
(German technical supervisory authority)
to check the voltage of the lines of the
connection cord (safety information to be
observed!).
2. Remove possible congestion.
3. Pump may not be suitable for this liquid. If
feasible, the liquid should be thinned.
4. Make sure that the temperature of the
liquid being pumped does not exceed the
max. admissible value.
5. Eliminate causes of dry-running.
1. Remove solids.
2. Refer to section 3.3.
3. Refer to section 3.4.
4. Make sure that mains voltage matches
that indicated on the type plate.
5. Please contact the customer service
department.
